Group Apomecynine. 
Genus AcrenNnopsis, Thomson. 
Thomson, Archives Entom. 1. p. 302. 
This genus is tolerably well known to students of the Lon- 
gicornes under the name of Talepora of Dejean’s catalogue. The 
body is of an elongate-elliptical shape with obtusely rounded 
elytra, the apex of which is adorned in most of the species by a 
black spot, margined anteriorly with pale ashy, the pale streak 
existing in those species which are destitute of the black spot. 
The antenne, as is usual in the Apomecynine, are much shorter 
than the body, and filiform, with the terminal joints much abbre- 
viated, and the third of great relative length. The thorax is un- 
armed, the head small, with rounded vertex and forehead and 
retracted face. The claws of the tarsi are short and scarcely di- 
vergent.
